Auto calc

Here is my request.  Is anyone able to create a manual trading EA that auto calculates stops and take profits from atr value ...allowing the user to adjust inputs based on the timeframe?  If so, I may put this up later today.  It is for my brother. 

ATR value on indicator (ex: 0.0024) is read as pips...meaning 24 pips.  A 5 digit ATR reading like 0.00248 is read as pips 24.8 pips.  Using this logic, I would like to be able to adjust the inputs with calculations detailed below.

 Inputs:

Stop loss= (input value) x (atr value)

Take profit* = (input value)  x (atr value)

Trailing Stop = (input value) x (take profit)

Trailing Step = (input value) x (trailing stop)  

Please allow  the input value to have 1 decimal, like "1.5" or "0.2".

* Note: This EA should have Y/N option for using a fixed take profit, since there are times the user may want the trailer to do most of the work.  Even if the user selects no to using the take profit, the projected take profit should always be calculated as it is used in calculating the trailer.

Please have the inputs show what is calculated for each. 

Thank you
